Motor Protection Circuit Breakers - MPCBs

What are Motor Protection Circuit Breakers?

Motor protection circuit breakers (MPCBs) are electrical devices that are designed to interrupt or break an electrical circuit should an issue such as a short circuit, phase loss or an overload occurs within the motor that the motor circuit protection breaker is protecting. 

What types of MPCBs are available?

MPCBs are available for a wide range of motor sizes and installation types and are available with a auto-resetting feature which allows a motor to resume operation after a short period post an overload trip.

MPCBs are chosen based upon the full load current of the electric motor and the maximum possible short circuit current of the motor that is being protected. MCPBs are capable of withstanding the initial starting current experienced by a motor without causing an interrupt and for overload protection they feature a bimetallic strip that can be adjusted between two established values.
